Quan-T-Cell System by EUROIMMUN
The Quan-T-Cell ELISA used in combination with the Quan-T-Cell SARS-CoV-2 is an interferon-gamma release assay (IGRA) for determination of the IFN-γ release of SARS-CoV-2-specific T cells. The T cells in heparinised whole blood samples are stimulated using spike protein-based antigens, and the released IFN-γ is measured using a fully automated quantitative ELISA. The test supports detection of past contact with SARS-CoV-2 or an immune response following vaccination.
